Extreme poverty all over the world is concentrated in rural settings. However, studies about cognition in low socioeconomic status (SES) children are for the most part conducted in urban populations. This paper investigates, in a poor rural sample, what are the individual and socioenvironmental variables that make the difference in performance in a processing speed task. Forty four 5‐year‐old children were evaluated with a processing speed task; individual and socioenvironmental information was obtained from parents' interviews. Higher scores in the effortful control dimension of temperament were associated with higher performance in the processing speed task. No other individual or socioenvironmental variable predicted the performance. These results showed that effortful control is important in processing speed and suggest that in low SES rural contexts, low effortful control children would require stronger interventions. 相似文献

Drawing from resilience theory, we explored the strategies that Mexican immigrant youth used to cope with stressors from being undocumented. On the basis of semi-structured interviews with 30 high school students who emigrated from Mexico to the United States, we identified several stressors from being undocumented, including having limited opportunities, fear of deportation, and exposure to negative reminders of their undocumented status. To manage such stressors, students utilized individual coping strategies (e.g. diversion, reframing, normalizing). In addition, the families of undocumented youth employed various coping strategies to help buffer their children against stressors from being undocumented (e.g. protecting the family unit, positive future, emotional support, limited communication). From our findings, we developed a preliminary model that describes the stress and coping of the undocumented youth in this study, which can extend past theorizing on resilience and thriving, as well as inform the design of community-based programs and policies for undocumented youth and their family. 相似文献

Citation numbers are extensively used for assessing the quality of scientific research. The use of raw citation counts is generally misleading, especially when applied to cross-disciplinary comparisons, since the average number of citations received is strongly dependent on the scientific discipline of reference of the paper. Measuring and eliminating biases in citation patterns is crucial for a fair use of citation numbers. Several numerical indicators have been introduced with this aim, but so far a specific statistical test for estimating the fairness of these numerical indicators has not been developed. Here we present a statistical method aimed at estimating the effectiveness of numerical indicators in the suppression of citation biases. The method is simple to implement and can be easily generalized to various scenarios. As a practical example we test, in a controlled case, the fairness of fractional citation count, which has been recently proposed as a tool for cross-discipline comparison. We show that this indicator is not able to remove biases in citation patterns and performs much worse than the rescaling of citation counts with average values. 相似文献

This essay presents the theoretical framework and main results of a research on intercultural mediation which has been performed in eight multicultural classrooms of Italian secondary schools. Intercultural mediation is conceived as a form of dialogic communication which should empower empathic and equal relationships between the participants by changing the existent negative patterns (dialogic mediation). The empirical features of mediation have been investigated in the interactions between mediators and adolescents in the selected classrooms. The analysis demonstrated that some dialogic actions were effective in empowering students’ personal expressions, promoting effective reflections and new narratives about their relationships, and management of their conflicts. Two limitations of dialogic mediation emerged from the analysis: (1) dialogic actions were always effective in demonstrating mediators’ involvement and coordination with students, but they were only occasionally effective in promoting dialogue among students; (2) promotion of active participation was more frequently successful than coordination of reflection and conflict management. 相似文献

This study was conducted to examine the efficacy of an inexpensive educational print exercise intervention based on the Transtheoretical Model (TTM) for older adults. Secondary objectives of this study were to examine the quality of the print intervention and possible ways to improve it through survey techniques. This was a posttest survey design. Information about the Senior cise booklet was distributed to senior housing communities and recreation centers throughout Rhode Island. One hundred thirty-three posters and 5,280 pamphlets with return postcards for ordering the Senior cise booklet were delivered over a period of nine months. Individuals who requested the booklet were contacted via telephone two weeks following mailing to assess the efficacy and quality of the booklet. Ninety-eight individuals requested the booklet and 61 participants completed the evaluation (mean age = 73 - 5.3 years; 77.1% female). The majority of participants found the booklet of good quality, stated that it created an interest, and said it inspired them to actually engage in physical activity. Survey participants cited only a few main good points and negative points about the booklet in general. The use of an inexpensive educational print intervention (Senior cise ) based on the TTM was well received and successful in engaging older adults to consider and participate in physical activity. The positive and negative points cited about the booklet will allow other researchers a better insight into what can make educational print interventions successful. Experimental research designs are recommended to evaluate more fully the efficacy of future exercise based print interventions. 相似文献

This study examines the viability of utilizing a dynamical system model and heuristic parameter estimation algorithm to make predictions for maximum heart rate (\(\mathrm {HR_{max}}\)) and maximal oxygen uptake (\(\dot{\mathrm {V}}{\mathrm {O_{2max}}}\)) using data collected from a submaximal testing protocol. \(\dot{\mathrm {V}}{\mathrm {O_{2max}}}\) is widely considered to be the best single measurement of overall fitness in humans. When a \(\dot{\mathrm {V}}{\mathrm {O_{2max}}}\) assessment is not available, \(\mathrm {HR_{max}}\) is often used to prescribe exercise intensities for training and rehabilitation. In the absence of maximal cardiopulmonary exercise testing (CPET), \(\mathrm {HR_{max}}\) and \(\dot{\mathrm {V}}{\mathrm {O_{2max}}}\) are typically estimated using traditional submaximal prediction methods with well-known limitations and inaccuracies. For this study, 12 regularly exercising healthy young adult males performed a bout of maximal CPET on a cycle ergometer to determine their true \(\mathrm {HR_{max}}\) and \(\dot{\mathrm {V}}{\mathrm {O_{2max}}}\). Participants also performed a submaximal bout of exercise at varied intensities. A dynamical system model and heuristic parameter estimation algorithm were applied to the submaximal data to estimate the participants’ \(\mathrm {HR_{max}}\) and \(\dot{\mathrm {V}}{\mathrm {O_{2max}}}\). The submaximal predictions were evaluated by computing the coefficient of determination \({R^2}\) and the standard error of the estimate (SEE) through comparisons with the true maximal values for \(\mathrm {HR_{max}}\) (\({R^2 = 0.96}\), SEE = 2.4 bpm) and \(\dot{\mathrm {V}}{\mathrm {O_{2max}}}\) (\({R^2 = 0.93}\), SEE = 2.1 mL kg\(^{-1}\) min\(^{-1}\)). The results from this study suggest that a dynamical system model and heuristic parameter estimation algorithm can provide accurate predictions for \(\mathrm {HR_{max}}\) and \(\dot{\mathrm {V}}{\mathrm {O_{2max}}}\) using data collected from a submaximal testing protocol. 相似文献

One of the major conceptual difficulties of environmental education is its complexity. During a 20 h module of initial training gathering together primary and secondary school teachers this concept was highlighted. Some approaches have been tested, all dynamic and transferable. They are analysed and assessed. 相似文献

This research analyzed the network of psychosocial influences through which efficacy beliefs affect academic achievement. Parents' sense of academic efficacy and aspirations for their children were linked to their children's scholastic achievement through their perceived academic capabilities and aspirations. Children's beliefs in their efficacy to regulate their own learning and academic attainments, in turn, contributed to scholastic achievement both independently and by promoting high academic aspirations and prosocial behavior and reducing vulnerability to feelings of futility and depression. Children's perceived social efficacy and efficacy to manage peer pressure for detrimental conduct also contributed to academic attainments but through partially different paths of affective and self-regulatory influence. The impact of perceived social efficacy was mediated through academic aspirations and a low level of depression. Perceived self-regulatory efficacy was related to academic achievement both directly and through adherence to moral self-sanctions for detrimental conduct and problem behavior that can subvert academic pursuits. Familial socioeconomic status was linked to children's academic achievement only indirectly through its effects on parental aspirations and children's prosocialness. The full set of self-efficacy, aspirational, and psychosocial factors accounted for a sizable share of the variance in academic achievement. 相似文献
